UNITED NSTATES 'PATENT OFFICE Y j o f WELDERS HELMET Warner L. Keehn,Spokane,` Wash.4 Y Application November 19, 19.42;, S-erialjNo. 466,173f Claims.

This invention relates to a welders helmet. At the present time, helmetsworn by Welders are equipped with a sighting glass consisting of asingle sheet of `black glass vthrough which a Welder can see only when awelding rod is in contact with metal parts to be welded and a brilliantlight is created. This makes it diflicult for the Welder to properlyapply the. rod to parts to be welded and keep the metal parts in properrela-r tion to each other prior to formation of a weld;

was the parts must be set with the helmet lifted Fig; 'itisV asectionalview taken vertically through Fig. 6, oni the linel-l.

i This improved helmet hasv a body I formed of metal,` composition orother suitable material which isopaque 'and will .protect the face of aWelder from burns or other injuries incidentto 'welding `The head gear 2is of conventional formation and the body I is pivotally connectedWelder may see and thus properlyset the metalw pieces without swingingthe helmet up over his head during setting of the metal pieces.

Another object of the invention is to so arrange the black glass and thetinted glass that, after setting the metal pieces it is merely necessaryto tilt the head and thus bring the black glass into position for him tolook through or While bringing the Welding rod into Contact with themetal pieces. i I

Another object of the invention is to providey a visor for shielding thetinted glass and preventing the eyes of the Welder from being injuredbyglare passing through the tinted vglass during a welding operation.

Another object of the invention is to prov-ide construction.

Fig. 2 is a front elevation of the sightingwindow.

Fig. 3 is a vertioalsectional view on the line 3-3 of Fig.` 2. l

Fig. 4 is a perspective view of a visor andA mounting frame constitutingpart of the invention.

Fig. 5 is a horizontal sectional view on the line 5-5 of Fig. 2.

Fig. 6 is a front view of a modified embodiment Aof the invention foruse in welders goggles.

during a welding operal with opposite sides of the head gear by pins 3so that the helmet may be tilted vertically from lowered position inshielding relation to the welders` face, to raised position over hishead, when not in'use. Atv its front; the helmet I is formed with -asight opening surrounded by a window 4 which` projects .forwardly `fromthe helmet and,

at its rear, is .formed withabordering ange 5 by vWhichit is firmlyiixed to the helmet'. At the front of the window,` its Walls are bent toform an I inwardly. projecting `flange Y 6 terminating in 'aninturnedlip 1, and,` referring toFigs. 3 and 5.

it will be seen that since the flange is yieldable,

it may` have firm gripping engagement with sightling glasses andthef-rame of a-visor and hold vthem in place. f

The sighting glasses 8 and 9 fit within the window 4, one above theother, the upper glass being black and the lowerglass beingeither clearglass important thatit be protected from damage during a weldingoperation. After the glass I0 and the -unitedglasses 8 and 9 have beentted into the window `4, a frame II is fitted into place and secured( byfasteners .I2, which maybe screwsor bolts, and the ange I3 of this framefits closely against inner surfaces of glasses 8` and I9 andthe .glasseswillI be firmly held in place with the lip 'I of flange B bearingagainst the outer surface of the glass III.4 l 7 y i After the glasseshave been fitted into the window and secured by the frame Il, the frameIl, carrying a shield or visor I5, is applied. This frame and the visorare formed of resilient metal and the visor has free end portions I6which are free from end portions I'l of the frame and bent to extenddownwardly and rearwardly of the end portions of the flange 6. Whenapplying the frame I4, its end portions II are flexed rearwardly, asindicated by dotted lines in Fig. 4, and disposed against the outersurface of the glass I0, so that they may slide into place under theseend portions of -the flange. The frame is then shifted upwardly todispose its upper bar or strip under the upper portion of flange 6 andthe inner side edges of the frame will then be overlapped by portions ofthe lip 'I and the frame firmly held in place Awith the visordisposed.;in yfront o-f the window with its'end portions I6 bear'ingi againstouter surfaces of end portions of the flange 6. This visor overhangs theglass 9 in partial cover-- ing relation thereto, as shown in Fig. 3,and, when the helmet is in use, the Welder may hold his head at such anangle that he canvlook ,through the glass 9 and under the visor, inorder to see if the metal pieces to be welded are linv proper relationwith respect to each other and then accurately apply the welding rodthereto. As the rod is moved into engagement with the metal 'pieces tobe welded, the-Welder quickly lowers his head 'so' that'the black glassi'sbr'ought 'il'lt'o his line 0f vision and his eyes will notbeinjured'byth'e yflash which occurs duringzthe welding operation. The lshield or visor I'and its'end portions I6 serve `very,effectively toprevent glare from reaching the glass' 9' and passing through it intothe helmet. Itwill thus'be seen that a Welder wearing the .improved.mask may set the metal pieces torbe -welded and apply the weldingrodwiththe'helmet in position for luse infront ofV his faceand theglasses 8 and: Qbrought into hisr lineor vision 'v merely by` tilting:hisheadv upwardly or downwardly. When'neces'sary, the frame andthe-'visorA may be easily removed;

'Inf Figs. 6 andi 7 therev ha's'vbeen illustrated a modication of theinvention for 'use in welders goggles. In--this embodiment, a'black-'upper'glass I 8 and a tinted lower glass I9 arefused,theseglasses being cemented to each other andcut circular so'that theassembled glasses constitute a lens which will fit within theframe of apair of goggles. The visor is fixed to the glassf-I8along.

they lower 'edge thereof and projects forwardly at afdownward inclineinoverhanging relation to the upper portion ofther` glass I9.
